Comparing Cumulus VX to other Cumulus Networks Products

Cumulus VX is not a production-ready virtual switch or router. It has the same foundation as Cumulus Linux and Cumulus RMP, including all the control plane elements, but without an actual ASIC or NPU for line rate performance or hardware acceleration.

You can use tools like jdoo to monitor the virtual switch. The same automation, zero touch provisioning, security, and QoS tools are available.

The following table outlines the similarities and differences between Cumulus VX and other Cumulus Networks operating systems:
